1. You’ve just been promoted to be the line supervisor for Ames Awesome Candies Company. Immediately, you get a call that Finance noticed a cost variance in your department. It appears that you are consuming too few ingredients for your scheduled output. A box of Special Mixed Candies is supposed to be 140 ounces, and your annual bonus is paid on how close you manage your per/unit costs.
